Carries Easily Everywhere

Its slim, lightweight profile fits in standard car cup holders, bike cages, and your bag's side pocket without adding bulk or weight.

Yamaco was founded in Kyoto by master artisans who believed everyday objects should elevate daily life. We created this bottle to solve a modern problem: cheap plastic bottles that make water taste flat and contribute to waste. Our team spent 18 months sourcing only Japanese materials—borosilicate glass from a 100-year-old factory, food-grade silicone that passes Japan's strict JIS standards, and stainless steel caps tested for 10,000 open/close cycles. Every bottle is hand-inspected in our GMP-certified workshop. This commitment to authentic Japanese craftsmanship has made it the top-rated glass water bottle in its category for 3 consecutive years, with over 15,000 verified 5-star reviews praising its design and durability.

The Yamaco Mt. Fuji Glass Water Bottle - 400ml is primarily composed of high-quality borosilicate glass, which serves as the main structural material due to its exceptional durability, thermal shock resistance, and non-porous nature that prevents absorption of odors or flavors. This glass composition ensures purity and clarity, allowing users to enjoy beverages without chemical leaching, making it ideal for both hot and cold drinks. The bottle features a stainless steel screw cap, often made from food-grade 304 or 316 stainless steel, which provides a secure, leak-proof seal and corrosion resistance for long-term use. Additionally, a silicone gasket or seal is typically incorporated within the cap to enhance airtightness and prevent spills. The exterior design elements, such as the Mt. Fuji illustration, are applied using non-toxic, lead-free ceramic paints or decals that are baked onto the glass, ensuring they remain vibrant and safe during use. These ingredients collectively offer benefits like maintaining beverage temperature, preserving taste integrity, supporting eco-friendliness through reusability, and providing a visually appealing, authentic Japanese aesthetic that enhances the user's hydration experience.
